GEORGE N. Jess, OF LANCASTER, OHIO, ASSIGNOR TO THE EAGLE MACHINECOMPANY, OF-SAME PLACE.

FODDER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 357,009, dated February1, 1887.

' Application filed July S2 9, 1886. Serial No. 209,440. (So model.)

To' all whom it may concern.-

Be it known that I, GEORGE N. J oss, of Lancaster, Fairfield' county,Ohio, have invented a new and useful Improvement inFodder-Outter's, ofwhichthe following is a specification.

My invention relates to improvements in machines-which, under variousdesignations of cutting-boxes, feed-cutters, &c., are

' machine is shown set for the manufacture of fine, and in Fig. 2 forcoarse, chop-feed. Fig. 3 is a section in the plane of the axes of thefeed-rollers, the upper roller being shown uplifted and tilted. Fig. 4consists of detached representations of the driving-pinion and portionsof the flexible coupler and of the guidingbearing of the upperfeed-roller. Figs. 5 and 6 are respectively an axial section, and a section on the line 6 6 of Fig. 5, ofafrictioncoupling of the fly-wheel tothe drive-shaft. Fig. 7 is a perspective view of the hanger on thedrive-shaft.

A may represent any suitablestand or supporting-frame, and B, O, and Dmay respectively represent customary or any suitable feedbox,box-covers, and discharge-spout. J ournaled horizontallyin'said frame isa drive-shaft, E, whose ends extend beyond the sides of the frame forattachment at one end of a heavy fly-wheel, F, and at the otherend of adrivingpulley G, and a cog-wheel, H, and for suspension of anadjustablehanger, N.

The office of the fly-wheel F is accumulation of momentum sufficient tocarry the knife through thick and refractory objects, such as knottystalks, corn-oobs, nubbins, 8m.

To guard against liability to destruction of the cutter by theaccidental presence of so obdurate an object as a stone or an iron bolt,the attachment of the said fly-wheel to its shaft is purposely such asto slip or give way under excessive resistance. Vith this object in viewthe said fly-wheel,instead ofbcing keyed firmly I to the shaft E, isattached as follows: The hub of the fiy-wheel has two orifices, J J,which, commencing at one side, which is made flat, pass entirely throughthe hub, and at the other side of the hub are broadened, so as tocoalesce and form a single wide opening, J. The shaft E has acircumferential groove, K.

L is a U'formed screw-bolt having nuts M.

The fiy-wheel having been placed in position.

on theshaft E, and the bolt L being inserted v in the cavity J J J", thenuts M are applied and are screwed home with force sufficient to securethe desired friction of the curved portion of .the bolt against thegrooved part of shaft E. This friction may manifestly be modified at anytime by simplytightening or slackening the nuts M.

Depending from and capable of free vibration on shaft E is a hanger, N,upon whose studs 41 are journaled a train of cog-wheels, H H H of whichthe last-mentioned gears to a cog-wheel, H secured upon shaft 0 of thelower feed-roller, P, which shaft revolves in stationary bearings a inthe frame or box. A'cog-wheel, H", on the shaft 0 gears with acog-wheel, H, j ournaled on a stud-projection,

71 from a bracket, a. A link, Q, is pivoted on stud h, and has at itsupper end a stud, h, on

which is jonrnaled a cog-wheel, H, which gears with cog-wheel H. Thecog-wheel H" is also journaled in a guiding-bearing,R,which is pivotedon stud h, and whose annular interiorfianges,r,engagein correspondinggrooves, s, in a cog-wheel, S, which is thereby maintained in accuratemesh and alignment with its driver H.

The cog-wheel S has a central orifice, T, which is occupied by aspherical or rounded knob, U, on one extremity of shaft V of the upperfeed-roller,W. Spurs u from the knob U, occupying cavities orindentations t in the orifice T, compel corotation of feed-roller Wwit-h that of the cog-wheel S, whatever angular position the saidfeed-roller may from time to time assume. \Vhile angular changes of saidfced-roller are thus provided for, changes in heightare permitted by thedescribed link and gniding'bearings Q and R. Slots a in the box restrictthe shaft V to vertical displacements, while the walls of theguiding-bearing It coact with the spurs u to limit the longitudinaldisplacements of the feed-roller V.

On the side of the box remote from the driving-gearing the shaft Vprotrudes sufficiently to receive a downwardly pressing spring, X.

For the manufacture of the coarser kinds of chop-feed the wheel H may betaken off, so as to bring the wheel H in direct mesh with the wheel H".In this arrangement of the driving -gea1's the wheel I-I becomes anidler To enable the movable train of cog-wheels H, &c., to be readilyshifted and securely held to the desired mesh with the stationary train,the hanger N is connected by red Y to a lever, Z, which is retained toany particular adjustment by engagement of a springcatch, 1, in theappropriate notch of asegmentrack 2.

By substituting cog-wheels of diverse diameters in place of the wheel Hthe machine may be adapted for any variety of coarse or fine cutting. Byremoving said cog-wheel I m and retracting the lever Z the cogwheel Hmay bebronght directly into gear with the cogwheel H", thereby giving alargely-increased speed of feed-rollers relatively to that of the cutterand fitting the machine for production of correspondingly coarserchopfecd.

I claim herein as new and of my invention in fodder-cutting machines 1.The combination, with the box or frame, of upper feed-rollerlV and itsshaft V, said frame being provided with vertical slots a, occupied bysaid shaft, rounded knob U,

armed with spurs a, cog-wheel S, having an indented orifiee,'I t,occupied by said knob,and annular grooves s, guiding-bearing R, havingflanges 1 corresponding to and received by said annular grooves,cog-wheel H ,intermeshing with cog-wheel S, cog'wheel H, havingconnection with said cog-wheel H by link Q,

and gearing connecting cog-wheel H with U the drive-shaft, substantiallyas set forth.

2. In a feed-cutter, the combination, with the cutter-shaft, the lowerfeed-roller shaft, and gearing situate between the two, of the upperfeed-roller shaft provided with a spurwheel, a cog-whecl having acentral orifice and indentations arranged around the sides of saidorifice and adapted to receive the spurs on said spur-wheel, gearingsituate between the lower feed-roller and said cog-wheel, aguide-bearing loosely connected with the upper feed-ro1ler shaft, andwithin which is received the said cog-wheel, and a link pivoted to theframe of the feed-cutter and to said guide-bearing, substantially as setforth.

3. In a feedcutter, the combination, with the cutter-shaft, the lowerfeed-roller shaft,

and gearing situate between the two, of the upper feed-roller shaftprovided with gearing, a stud on the frame of the machine, a cogwheelthereon engaged by the gearing on the lower feed-roller shaft, a linkpivoted also to said stud, a stud on said link on which is mounted acog-wheel, which latter is engaged by the gearing on the upperfeed-roller shaft, and a guide-bearing pivotally connected with thelatter shaft and with the stud on said link, substantially as set forth.

In testimony of which invention I hereunto set my hand.
